This book is a psychological exploration of unusual minds a religious exploration of
demonological myth and a philosophical exploration of the reaches of pragmatism. It uses
topics such as hypnotism mediumship and mass possession to argue for a comprehensive
understanding of the demonic that acknowledges not only the creativity which it encourages but
also the danger it can bring. Professor Ruetenik uses James' religious pragmatism to evaluate
the relevance of psychical research and to explain common beliefs regarding demons spirits
and other controlling personalities.The conclusion of this interdisciplinary research is as
alarming as it is fascinating: When exploring the demons of William James we discover that
ordinary personality cannot be clearly separated from what we consider the demonic.
